A UK business directory operated by Thomson Directories Ltd, trading since 1980. The free listing is real but expressly time-limited to three months, and the operator distinguishes owner-created "listings" from third-party "citations" that make up much of the database.
Domain Rating is a dated Ahrefs snapshot of domain authority. PetroHrys Score is an independent editorial assessment of the directory’s practical business value. They are separate measurements and are never combined. Domain Rating values are dated historical Ahrefs snapshots. Domain Rating is a dated historical measurement of the shared domain, not an assessment of this individual registry page. New measurements are not collected because the Research Center does not depend on mandatory authenticated APIs. Where several registries are published on one measured domain they repeat that domain’s single dated snapshot rather than each carrying a figure of its own. Domain Rating is a third-party metric produced by their respective providers, not by PetroHrys.com. Each recorded value carries its provider and the date it was measured, and describes the domain that was measured rather than one page on it. No source has been consulted for authority score, estimated traffic and referring domains, so they are not published for any record.
The free route is a real submission form with business name, address, phone, email and category fields — not merely an enquiry button.
The operator is unusually open about where its data comes from, separating owner-supplied listings from bought-in citations rather than presenting the whole database as owner-managed.
The submission form asks explicitly whether you are the business or a third party, which at least records provenance at the point of entry.
Limitations
The free listing EXPIRES. The operator describes it as “A three-month time limited free business listing”, so it is not a permanent presence and no permanence is asserted here.
The free listing does not include a link to your website. The operator footnotes its own comparison table: “Website link is available when purchasing a thomsonlocal backlink product or paid advertising”.
Much of what appears in search results was never supplied by the business. The operator states: “Listings are directory entries whereby the owner of the business or organisation has a direct relationship with Thomson Local. Whereas citations are provided from a third party.” It names 118 Information Ltd as the source of most citations.
Beyond the website-link footnote, the free-versus-paid feature split is rendered by the page’s styling rather than stated in text, so which specific features a free listing includes is NOT established and is not asserted.
A third party may submit a business: the form offers “I am promoting this business on behalf of someone else”. An entry is therefore not evidence that the named business created or approved it.
Whether verification is required, and by what method, is not documented by the operator, so nothing about verification is asserted.
Businesses can reply to reviews, but the operator’s own wording bounds who: the review form promises “Get notified - if an advertiser responds to your review”. Responding is documented for ADVERTISERS, and whether a free listing can reply is not established.
A listing is a directory entry. It is not evidence that a business is solvent, currently trading, licensed, or checked beyond what the operator documents here.
No ranking, indexing, traffic or lead outcome is asserted. The operator markets outcomes; this record does not adopt them.
The operator states a free listing can be live “in as little as 48 hours” after applying. What is checked in that period is not documented.
Best for
UK local businesses wanting a free entry in a directory with a named, long-established operator.
Businesses that want to understand exactly what a free tier excludes before paying for anything.
Not recommended for
Anyone who needs a permanent free listing. The operator states the free listing is time-limited to three months.
Businesses whose main reason for listing is a link to their own website. The operator states that is a paid feature.

Establishing required submission assets requires submitting a listing and observing the result. That has not been done for any directory in this dataset, so it is not published rather than estimated.

The PetroHrys Score is a first-party editorial assessment, not a third-party
authority metric. It is the weighted sum of the ten factors above, divided by ten, so the number
on this page is reproducible from the values shown. Each factor is scored from 0 to 10 by a human reviewer and weighted as shown. The definitions describe what was weighed, not a rubric: no threshold or formula maps a directory onto a value, and two reviewers could reach different numbers. The score is reproducible from the factors shown on every record, but it is an editorial judgement, not a measurement.
